Deprivation

The most recently available deprivation data are from the 2015 English Indices of Deprivation and this shows relative deprivation at small areas (LSOAs). Data on household deprivation comes from the 2011 census and can be found in the census demographics section of the JSNA website.

The Indices of Deprivation is an area-based measure of relative levels of deprivation in small areas, (Lower Super Output Areas (LSOAs), which contain approximately 1,500 people). It can be used to compare the deprivation across different areas, identify the most deprived areas within a larger geography (for example in the CCG), and to examine which domains of deprivation are more or less prominent in an area. The Indices cannot be used to quantify how deprived an area is (nor can it say by how much one area is more deprived than another), and there are different indices of deprivation for Wales, Scotland and Northern Ireland (so comparisons cannot be made across countries).

The indices are published by the Department for Communities and Local Government every 3-4 years and are widely used, notably in funding allocations and targeting. The most recent update is the ID2015, released in September 2015 using data mostly from 2012/13. ID2015 is made up of seven domains of deprivation, although each domain is not given equal weighting. From these, an overall score of small area deprivation is calculated; these are then ranked from most deprived (1) to least deprived (32,844). It is important to note that the indices measure deprivation and not affluence (the least deprived area may not necessarily be the most affluent).

Domains contributing* to the overall Index of multiple deprivation:

Income (22.5%)

Employment (22.5%)

Health Deprivation and Disability (13.5%)

Education, Skills and Training (13.5%)

Crime (9.3%)

Barriers to Housing and Services (9.3%)

Living Environment (9.3%)

*the weights used to calculate how much each domain contributes to the overall score is included in brackets

GP practices do not have established geographical boundaries (e.g. people residing in one area may be registered to GP practices outside of their local area and more than one GP practice may operate in a single area). However, using the January 2016 release of residential location of GP registered patients, it is possible to create a deprivation score for each GP practice ‘reach’.

The GP Practice deprivation score is the registered population (as at 31st December 2015) weighted by ID2015 score, as a proportion of the total population registered to the GP. This is calculated by taking the deprivation score for every LSOA where a GP has registrations multiplied by the number of registrations for the GP in that LSOA and dividing this total by the number of people registered to the GP.

The figure below shows GP practices within each CCG in West Sussex by their national decile group (practices in dark blue are estimated to have the most deprived populations in England whereas those in orange are the least deprived).

The table below shows the number of practices in each deprivation decile for West Sussex CCGs.
